Most of this seems to be about the physical help the children of Israel received as they left Egypt. However the line that “the snare is broken” lends itself more to a spiritual interpretation as that is how the phrase is used.

They shall not dwell in your land, lest they make you sin against me; for if you serve their gods, it will surely be a snare to you.” Ex. 23:33

Take heed to yourself, lest you make a covenant with the inhabitants of the land whither you go, lest it become a snare in the midst of you. Ex. 34:12

And you shall destroy all the peoples that the LORD your God will give over to you, your eye shall not pity them; neither shall you serve their gods, for that would be a snare to you. Deut. 7:16
